Restaurant Recs near City Park/Downtown in Denver

Will be visiting DD and new boyfriend who live near City Park in Denver. Will have car. Looking for restaurant recs where I can take everyone out for a "treat" dinner. They both eat meat, however gluten free. Any cuisine except Indian. Good value for money desired. Thanks in advance for your help!

17th Ave/Uptown area has great food. My personal favorite is il Posto, a small Italian place with a young, inventive chef. Italian with a modern flair. Not sure about gluten-free but this is a common request in Denver and likely can be accomodated there. I have head Olivea is great too but have not been there yet. Downtown I would suggest The Kitchen, Rioja, Osteria Marco, or Tag.
